A shown Clearly in Fig.2; the container 15 insertecl through the Well of the furnetfce and disposed therein so that one end will project beyond the furnace shell, this proj'ecting end being fitted-around a collar or ring-*8 which is preferably of brass or alum; inu'n so thet'it Will Withstantlthe effects of iijioi'stii re (incl Will not I impart "excessive Weight "to the apparatus. The end of the eontainer is secured around this collerbr r ng lOy-cap screws 9 inserted throughthe container shell into the rln as shown inay then he bre'zeclorso'deredso tha'ti'a water tight jbint Will be efiected. This outer end of the container is 'closedby 2i heed plate 10 secured to the ring or collar 8 cap screws- 11 and having" a gasket'lfi interposed between their to attain water-tight joint. The; lfeed plate lO carries the regulating yal've and Water supply controlling "e'lefnents, as r i f be hereinafter fullyfclescribecl, Secured to op osed fades so as v the back plate 5 isa, plate orflange 13 which 7 'close age-inst thefu'rnece shell a n' d ei'ztei il is preferablyfastenecl in place by rivets l l,

over the slot 17 to cover the same. This supporting strip 2 is preferably a sheet 'metal tape or ribbon provided with an open stood upon reference to Figs. 2 and 4. The

parts having been assembled as described, the ribbon or supporting strip 20 is moved vertically through the channel 19 of the plate 18 until the container 4; is level, and the upper end of the strip is then bent over the upper end of the anchor plate 18, as clearly shown in Fig. 2, thereby maintaining the container 1 in its level position.

This manner-of supporting the inner endof the container is advantageous inasmuch as it is very simple and permits the container to be easily and quickly brought into a true level position, thereby tending to prevent overflow and permitting the use of a container of large capacity. This particular means for supporting the inner end of the container is especially desirable when applying the device to old furnaces which may have settled unevenly inasmuch asthe container can be brought into a true level position notwithstanding the uneven mounting of the furnace. The outer erd of the container is secured firmly to the furnace shell bv a clip or bracket 21 which is bolted or otherwise secured to the furnace shell and to the top of the container, as clearly shown in Fig. 2. The exact manner of s curing the clip is immaterial but if sheet metal screws be employed such screws will cut their way through the metal of the container and thereby firmly engage the same so that loosening or withdrawal will be prevented.

'The ring 8 and the head plate 10 will preferably be castings of brass or. other non-corrodible metal in order that the neoessary rigidity and durability will be attained. The head plate is formed with an for the summer or cleaning or repairing may be necessary; Resting upon the trough 23 so as to coverfthe open top thereof is a bottom plate 25 which is secured to the trough by, screws 26, as shown in Fig. 2. This bottom plate 25 has its upper surface recessed to provide a seat 27 for a cylinder 28 of glass or the like which constitutes a in the dependingportion of this bracket is formed a flared opening 83 which receives the outer end of a float rod 34 extending longitudinally of the trough 23 and into the This float container 1 to carry a float 35. 35 may be of any approved style and is preferabiy'a rear elongated body of ircular cross section. The opening 33 in the supporting bracket 32 is of suflicient diameter to permit free movement of the float rod and accommodate the angular relation of the same to the plunger rod 31 so that bending of the plunger rod or' binding of the same in the guides through which it works will be avoided. It will be understood that the lower end of the plunger rod 31 is pivoted to the float rod, as shown at 36, and the plunger rod rises through the ,opening 30 a and passes into a valve chamber 37 over the sight tube 28. It will be understood. that the plunger rod and the float rod are connected as the parts are assembled. After the sight tube or cylinder 28 is in place, a central plate 38 is fitted over the upper end of the sight tube, packing being interposed between the said plate and the upper edge of the tube 28, as will be understood. This plate 38 is connected with the bottom plate 25 by long bolts 39 inserted through and engaged in themarginal portions of the respective plates so that, when these bolts are turned home,the plates 25 and 38 will be firmly clamped together and to the sight tube 28. The plate38 has a drip opening 40 formed therethrough and preferably a nipple or drip nozzle 41 is formed on the under side of the plate around the said opening. The plate 38 is provided on its upper side with a boss or cylindrical guide 42 for the plunger rod'and a guide opening is formed through the plate in axial alinement with the bore of the said uide. cured upon the upper end of the plunger rod 31 is a plunger head or governor valve 43 having a gasket 44 resting on its upper end and held thereto by inturned flanges 45 formed at the upper end of a sleeve 16 which fits snugly around the plunger head or valve body 43 and depends below the Se- I sameto fit around the guide 42 and con 2 stitute a water shed whereby the water will be prevented from dripping into the opening around the plunger rod.

After the new filtering agent is placed in position, the cap is returned to place and secured by the screws 65 as before. 7 If, through lon -continued use, the packing 44 should be worn, the bolts 51 may be withdrawn, whereupon the entire upper section of the device may be lifted slightly and swung about the water supply pipe 63 thereby exposing the governor valve. The body 87 may then be lifted from its place giving access to the screw 4&7, the removal of which will permit theguiding and water-shedding sleeve 46 to be withdrawn. New packing may then be easily placed upon the head or valve 43 and the parts restored to their normal positions by reverse operations. It may be necessary after several years use to clean deposits-from the container 4. By removing the'screws- 11, the plate and all the parts associated therewith may be swung to one side without disconnecting the water pipe so 7 that a scraper may then be inserted into the containerand manipulated to withdraw the deposits. If the bracket or clip 21 be removed, the container niay be rotated about its connection with the supporting arm 16 so as to be entirely withdrawn and subjected to a more thorough cleaning. 7

To avoid trapping of air within the governor chamber 37, a vent 66 is formed through the bottom and side of the filter body, and to take care of possible overflow which might occur through failure to cut off the inflow of water when the furnace has been shut down, I provide an opening 67 through an upper portion of the plate 10 and on the outer face of the said plate around the said opening form a small spout 68. In the event that such overflow should occur, the water will be directed by the spout 68 onto the cellar floor and will eventually reach the cellar drain, the arrangement directing the water away from the shell of the furnace so that rusting of the furnace under these conditions will be avoided.
